Sparkfun Configurable OpAmp Board - TSH82

The SparkFun TSH82 Configurable OpAmp Board was designed to give the best combination of performance and flexibility that could be achieved by giving two gain stages, each one independently accessible on the header pins. Each stage is natively configured as an inverting amplifier that can also be strung together to expand the capabilities of the OpAmp.

Electrically speaking, both stages on this board are identical. The default configuration is inverting with a gain of -4.7 with a bandwidth of almost 10MHz. Input signals are AC coupled, possess an input impedance of 10K with a low frequency cutoff of 15.9Hz. Outputs are also DC coupled, so add a capacitor to the output if running a single-ended supply and need to strip out the DC component.

On the back of the board you’ll find 10 solder jumpers that can be used to change the board’s performance, but nothing there needs to be changed to use it in it’s default state

Features of TSH82 Configurable OpAmp Board

• Input signals possess an input impedance of 10K with a low frequency cutoff of 15.9Hz
• The board can operate with a single-ended DC power supply of 4.5V to 12V, or a bipolar supply from +/-2.25V to +/-6V
• Jumpers on the back of the board can be used to configure each stage for non-inverting operation, differential input, and DC input coupling
